Add new vlan in functionnal ERPS ring : Precaution

naicoram01 — Thu, 11 Mar 2021 18:14:24 GMT

Hello,

I want to modify protected vlan by adding a new one in switchs configured with an ERPS ring and I want to know the risk with this modification and what precaution to have doing this configuration.

the switchs used in this ring is BD8810 and X690.

Thank you so much for your support guys.

Best regards,

Hi,

Unfortunately I don’t remember much of Black Diamond switches and the old EXOS but you may or may not have to disable ERPS ring to add another protected VLAN. You can refer to the exact EXOS version User Guide or Command Reference Guide by picking the version from a dropdown list here: https://www.extremenetworks.com/support/documentation/extremexos-30-7/

Other than a bit of loop prevention downtime (ie. a loop if you didn’t put one port in a ring manually), I don’t think there would be any impact.

Hope that helps,

Tomasz

Hi Tomasz,

thank you for your reply.

for information the conf of the erps is already done and the loop if loop free.

I have to add other new protected vlan in the loop(in all the loop’s node) and I want to know if I have to do something else other than adding the “protected vlan xxx”.

in other world, is adding new protected vlan in a loop free ERPS does generate a destabilization of the loop ?

thank you.

Hi,

If you do ‘configure erps ringname add protected vlan vlanname’ it shouldn’t affect the loop protection.

Hope that helps,

Tomasz

Hi Tomasz, Hi to everyone who want to help 🙂

I was thinking about another detail; what about the tagging the vlan in the port used in the ERPS conf ? Do I have to tag the vlan and after add it as protected in the erps or the opposite, add the vlan as protected in the ERPS and tag it ?

configure vlan Vlan_NAME add ports 19-20 tagged
configure erps ERPS_Ring add protected vlan Vlan_NAME

configure erps ERPS_Ring add protected vlan Vlan_NAME
configure vlan Vlan_NAME add ports 19-20 tagged

Thank you in advance for your reply.

Best regards,

Hi,

I think both should be fine as long as in first place you make sure that RPL Owner is already protecting the VLAN before all nodes are able to forward its frames. I’d recommend the second approach starting with RPL Owner.

Hope that helps,

Tomasz
